strips are to be folded or relatively moved in order to accomplish the desired result.

Another object of the invention is to provide a puzzle of this kind comprising a series of pivotally connected strips constituting what may be termed a frame together with a pair of additional strips pivotally connected to each other and to adjacent strips of the frame, the purpose of the puzzle being to bring the last two strips within the frame or to a position outwardly of the frame.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in plan of my puzzle showing a pair of strips exteriorly of the frame;

Figure 2 is a plan view showing an initial adjustment of the strips of the frame in solving the puzzle tobring the pair of strips within the frame;

Figure 8 is a view in plan illustrating another step in solving the puzzle;

Figure 4 is a view in plan illustratmg a still further step in the solving of the puzzle;

Figure 5 is a view in plan illustrating still another step in solving the puzzle;

Figure 6 is a view in plan showing the final step.

As disclosed in the accompanying drawings, my improved puzzle comprises a frame member F consisting of a pair of elongated members or strips 1 having adjacent end portions pivotally connected, as at 2. At a desired point intermediate the ends thereof the strips 1 have pivotally connected thereto, as at 3, the extremities of a pair of str ps 4, the opposite or outer extremities of whlch belng pivotally connected as at 5. The distances between the pivotal connection 3 and the pivotal connection 5 are the same.

As particularly illustrated in the accompanying drawings,it is to be noted that one of the strips 4 overlies one side face of a strip 1 and the second strip 4 overlies the opposite face of the second strip 1. I I

The outer end portions of the strips 1 have pivotally connected therewith, as at 6, the 60 strips 7 ,the opposite extremities of which being pivotally connected, as at 8,,to anaddi tional strip 9. I, 1

The strips 1, 7 and 9 are comprised in the frame F and thepurpose of thepuzzle is 6 5 to so adjust these strips to position the strips 4 either outwardly of the frame, as indicated in Figure 1, or to a position disposed inwardly thereof, as illustrated in Figure 6, or viceversa.

It is to be noted that one ofthe strips 7 overlies the side face of the strip 1 opposite to that with which the end portion ofthe adjacent strip 4 overlies. Bythis arrangementonestrip 7 overlies a face of one of the strips 1 and the second strip 7 overlies the opposite face of the second strip 1.} As clearly illustrated in thez'drawings, one end portion'of the strip 9 overlies one face of a strip 7 and the opposite endportion of" said strip 9 overlies the opposite faceof thesecond strip 7. It is to be noted thateach of the strips 7has its extremities overlying the, sameside faces of the strips 9' and l with which it is associated.

'With the d'evice in the assembly as illustrated in Figure 1 with the pair of strips 4 outwardly, disposed with respectto' the frame F, it is the purpose of the puzzle, as herein before stated,to.so adjust the various strips to arrange the strips 4 inwardly of the frame as illustrated in Figure 6 Figure 20f the drawings illustrates in plan substantially the first step in solving the puzzle which consists in moving the pivotal connection 2 in a direction away from the-pivotal connection 5 between the strips 41a nd swinging one of the pivotal. connections 8 in a general direction toward the strip4 remote therefrom. This movement is continued until the pivotal connection 8 just referred to is positioned substantially in register with a pivotal connection 6 remote therefrom when the frame F is in its extended position as illustrated in Figure 1.

This operation results, of course, in a fur ther relative contraction of the strips 4:, strips 1 and the second strip 7 into substantially a diamond shape as illustrated in Figure 3 with the first link 7 and the strip 9 superimposed one upon the other. 7

While not necessary I findit of advantage to swing the superimposed strips 7 and 9 into a reverse position, as illustrated in Figure 4:,

.and then to pull tQWard the rightthepivotal connection between the superimposed strips 9 and 7 resulting in the arrangement of the various strips asparticularly illustrated in Figure 6., To' return the strips" 4 to the position as illustrated inFigure 1,the steps hereinbefore recited are reversed.

-In the present embodiment of my invention it is tobe notedthat the distances between the pivotal connections 6 and 8 and 8, 8

are the same but'that each of such distances is less .thanthat of the space between each ofrthe pivotal connectionsB and 5. s

I also find it of advantage, to further increase the attractiveness of the puzzle, to pro- Vide along the marginal portions of each of the various strips different identities 10, such as lines. The identities of each of the strips may be different in any desired manner, as by color, formation, or otherwise which will readily distinguish one from the'other. It is to be noted that these different identities 10 of each of the strips are so'arranged that when the puzzle is in one finished adjustframe strips between the ends thereof, the pivotal connection of the remaining frame strips to said adjacent frame strips being on opposite sides of the latter. 7 2. A puzzle consisting of at least five strips pivotally connected end to end to form a closed frame, certain of said strips having an adjacent strip at one end thereof engag ing'one face thereof and'the adjacent strip at the opposite end engaging the opposite face thereof and at least two other strips pivotally connected together at one end thereof and having the free ends pivotally connected to adjacent frame strips intermediate the 'ends'of' the latter, the pivotal connection 0f. one of said. two other strips to said frame-strip being on the side of "the frame opposite from the connection of the other of said two strips, and the connection of said two other strips to each. other-being on sides of the same which are opposite to the sides connected'to the frame strips.

In testimony whereof I hereunto aflix my signature. LOUIS T. KRAUSE.

ment, as in Figure 1, similar identities of all of the strips extend along the outer marginal portions thereof, while when the puzzle is in its second finished adjustment, as in Figure 6, the outer marginal portions of all of the strips are substantially defined by the 2 other lines 10. H V i -From the foregoing description it is thought ,to be obvious that a puzzle constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled andoperated, and it will alsobe obvious that my invention is sus- 1; A puzzle consisting of five or more strips pivotally' connected end to end to form a closed frame, and two other 'stripspivotally connected, together 7 and to two adjacent
